Re: Workstations booting with UEFI don't tftp lts.conf

To answer my own question, the problem was that for the UEFI booting, my
pxelinux.conf/ config for booting ltsp looked like:

kernel http://123.456.78.9/ltsp/amd64/vmlinuz
append ro initrd=http://123.456.78.9/ltsp/amd64/initrd.img-generic
init=/sbin/init-ltsp forcepae root=/dev/nbd0

The place where LTSP retrieves the lts.conf file is
in /usr/share/ltsp/init-ltsp.d/05-getltsconffile and this fails to parse
the http:// string properly.
So I slightly modified 05-getltsconffile to work for both my cases, and I
hope for all the original cases it worked for:

# diff 05-getltsconffile
/opt/ltsp-old/amd64/usr/share/ltsp/init-ltsp.d/05-getltsconffile

< # The path may also be part of a URL so also need to remove leading
'proto://host'
< # If there is no path, we want just "lts.conf" without inserting a slash,
as some tftp
---
> # If it doesn't, we want just "lts.conf" without inserting a slash, as
some tftp

<     boot_image=$(cat /proc/cmdline | sed -n
's/.*BOOT_IMAGE=\([^[:space:]]*\).*/\1/p' | sed 's#^[^:]*://[^/]*##')
